DEVICE AND METHOD FOR CONTROLLING AN INJECTED FUEL QUANTITY IN A FUEL CELL REFORMER ONBOARD A MOTOR VEHICLE

摘要

Device for controlling an amount of fuel injected into a fuel cell system reformer (2) on a motor vehicle comprising an air compression unit for supplying air to the fuel cell (1) and a fuel cell electronic control (4). The electronic control unit (4) comprises: - an estimator (8) of the hydrogen flow rate (QestH2) at the outlet of the reformer (2) from input parameters comprising data delivered to the stack (1) or provided by the battery (1); and control means (10) for the amount of fuel (QCarb) injected into the reformer (2).
